P{EP}Mrp4EP3655 is inserted 47 bp upstream of the Mrp4 transcription start site and directs over-expression of Mrp4 in the presence of Scer\GAL4.
Flies expressing Mrp4EP3177 using Scer\GAL4da.G32 or Scer\GAL4Act.PU display a profound increase in recovery time after anoxia compared with controls.
No pupae form when Mrp4EP3655 is expressed with Scer\GAL4da.G32 under chronic hypoxia conditions. This is in contrast to controls which show no larval developmental defects and die during late pupal stages under the same conditions.
